Abstract
A system for sealing an access port of a pressurized container or conduit comprises a metallic caphaving a sealing surfacewhich forms a seal with a corresponding sealing surfaceof a metallic access port assembly, when the surfaces are pushed against each other by a clamping meanswhich is preferably separate from the cap. As shown the metal to metal sealing surfaces are frustro-conical in shape. The cap comprises a shoulderwhich engages the rim of the access port if the cap is over tightened preventing deformation of the sealing surfaces. The cap may comprise a further frustro-conical sealing surfacewhich co acts with a corresponding surfaceon an insertwhich fits within and rests upon an internal shoulderof the access port assemblywhich may be welded onto a container.
